Positive ovulation test when i technically shouldnt be ovulating..

I have been trying to track my ovulation for a few months now but my periods have been so irregular its been pretty impossible. This month my husband and i decided to just have sex everyday and see what happens. I technically should have been ovulation at the end of last week/this weekend. Yesterday and today i have been getting alot of strange cramping, unlike anything ive really felt before. So i took an ovulation test just to see what the outcome would be. It came out positive. Is it possible that we conceived at the weekend and that's why im getting a positive result? I cant take a pregnancy test until next week and im so impatient haha.
Thanks in advance for any advice or personal outcomes.
